应用程序 - ＆GT;相机 - ＆GT;照片 - ＆GT;低分辨率 [英] App -> Camera -> Photo -> low resolution

问题描述

问题：

当我用我的应用程序来拍摄照片并将其存储在SD，分辨率为160×120。 如果使用普通的摄像头，照片分辨率为1920x2560。

When I use my app to take a photo and store it on SD, the resolution is 160x120. If using camera ordinary, resolution of photos is 1920x2560.

所以，请大家帮我说了什么我必须做强制的摄像头，从应用程序开始，采取的标准高分辨率的照片？

So, please help me saying what I have to do to force camera, started from the app, to take a photo in the standard high resolution?

这是在code我用启动摄像头的意图和保存照片：

This is the code I use for starting camera intent and saving the photo:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    startActivityForResult(cameraIntent, CAMERA_REQUEST); 
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_REQUEST) { 

    Bundle xz = data.getExtras();
    if (xz!=null) {

    Bitmap image = (Bitmap) data.getExtras().get("data");

    String filePath = "/mnt/sdcard/DCIM/"; 
    filePath += "hml.png";
 try {
  image.compress(Bitmap.CompressFormat.PNG, 100, new FileOutputStream(new File(filePath)));
 } 
    catch (FileNotFoundException e) {
                 // TODO Auto-generated catch block
                e.printStackTrace();}  
    catch (NullPointerException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();       } 
    }}

谢谢你！

推荐答案

如果您不提供一个URI的输出图像，相机意图将返回的图片只是缩略图。按照有关如何正确做以下说明： http://www.tutorialforandroid.com/2010/10 /take-picture-in-android-with.html

If you don't supply a uri for the output image, the camera intent will return only a thumbnail of the picture. Follow these instructions on how to do this properly: http://www.tutorialforandroid.com/2010/10/take-picture-in-android-with.html
